This looks like a great addition to the EF lineup! However, I am concerned over the photo of the box. Obviously, this was taken with a lens that has an incredible front focus issue. I think we ought to discuss this. What's the AFMA needed to fix this? Which technique or software would you use to assess the problem? The picture should be much clearer. And the real deal breaker is whether this will be shipped with the newer "pinch" lenscap or the old one. Finally, if this was taken with a prototype of the 16-600, then obviously, we should all switch to Nikon!

The super telephotos and f/2.8 300s come in flight cases, which are encased in a large box, quite different from the smaller lenses. A 600mm f/2.8 would have a 214mm (8.5") wide front objective.

Impressive.

That actually doesn't sound too bad. If they got the DO part down right it could almost be usable.Too bad about the inevitable $30K price tag though.Sigh, no such thing as free lunch in telephoto land.
